100% of the resources in reddm1.arj and reddm2.arj are either modified versions of Doom/Doom2 graphics from id Software, or they've been "borrowed" from other pwads (see above "Additional Credits to" for a list of the sources).

Boring and really '95 because of all the plain graphical changes like changing the color of the guns and projectiles and turning a doom2 monster into a doom monster for variety for when somebody wants doom2 in doom like during that time period. As a result, this is probably illegal and breaks all the rules, including the ones set up by gamers.org. But who cares, anyway?
